If the caller does not have sufficient permissions to invoke the action, or the parameter values fall outside the specified
constraints, the action fails. The associated event attribute's cause parameter will be set to OPERATION_NOT_PERMITTED. For details
and example IAM policies, see Using IAM to Manage Access to Amazon SWF Workflows.

If set, specifies the policy to use for the child workflow executions if the workflow execution being started is terminated by calling the
TerminateWorkflowExecution action explicitly or due to an expired timeout. This policy overrides the default child policy specified
when registering the workflow type using RegisterWorkflowType. The supported child policies are:

TERMINATE: the child
executions will be terminated.

REQUEST_CANCEL: a request to cancel will be attempted for each child execution by recording a
WorkflowExecutionCancelRequested event in its history. It is up to the decider to take appropriate actions when it receives an
execution history with this event.

ABANDON: no action will be taken. The child executions will continue to run.

Note:

A child policy for the workflow execution being started must be specified either as a default registered for its workflow type or
through this field. If neither this field is set nor a default child policy was specified at registration time then a fault will be
returned.

The total duration for this workflow execution. This overrides the defaultExecutionStartToCloseTimeout specified when registering the
workflow type. The valid values are integers greater than or equal to 0. An integer value can be used to specify the duration in
seconds while NONE can be used to specify unlimited duration.

Note:

An execution start-to-close timeout for this workflow execution
must be specified either as a default for the workflow type or through this parameter. If neither this parameter is set nor a default
execution start-to-close timeout was specified at registration time then a fault will be returned.

The name of the task list to be used for decision tasks of the child workflow execution.

Note:

A task list for this workflow execution must
be specified either as a default for the workflow type or through this parameter. If neither this parameter is set nor a default task list
was specified at registration time then a fault will be returned.

The specified string must not start or end with whitespace. It must
not contain a : (colon), / (slash), | (vertical bar), or any control characters (\u0000-\u001f | \u007f - \u009f).
Also, it must not contain the literal string "arn".

Specifies the maximum duration of decision tasks for this workflow execution. This parameter overrides the
defaultTaskStartToCloseTimout specified when registering the workflow type using RegisterWorkflowType. The valid values are
integers greater than or equal to 0. An integer value can be used to specify the duration in seconds while NONE can be used to
specify unlimited duration.

Note:

A task start-to-close timeout for this workflow execution must be specified either as a default for the
workflow type or through this parameter. If neither this parameter is set nor a default task start-to-close timeout was specified at
registration time then a fault will be returned.

The workflowId of the workflow execution. This field is required. The specified string must not start or end with whitespace. It must
not contain a : (colon), / (slash), | (vertical bar), or any control characters (\u0000-\u001f | \u007f - \u009f).
Also, it must not contain the literal string "arn".
